Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ID-based sensing signal design is used, then the sensing RX node can obtain measurements and exchange information with the network entity, but the system complexity and latency increase due to excessive information exchange
Solution Approach 1:
The patent extracts the sensing state information directly from the received sensing signal at the RX node, rather than obtaining it through network entity mediation. The RX node processes measurements locally to determine its own sensing state, removing the complex information exchange loop with the network entity while maintaining measurement precision
Solution Approach 2:
The sensing RX node performs self-determination of its sensing state by processing measurements of the received sensing signal locally. This self-service approach eliminates the need for the RX node to exchange information with the network entity for state determination, reducing system complexity while maintaining accuracy
2Reliability
If ID-based sensing signal design is used, then the network entity can determine sensing state information, but the latency increases due to round-trip information exchange
Solution Approach 1:
The sensing state information is embedded in the sensing signal before transmission, allowing the RX node to extract and determine its state directly without waiting for network entity processing and response. This preliminary embedding of state information eliminates the round-trip latency while maintaining determination reliability
3Productivity
If state-based sensing signal design is used, then the RX node can determine its state independently, but the sensing signal must embed additional state information
Solution Approach 1:
The patent merges the sensing state information with the sensing signal itself, embedding the state data directly into the signal structure. This combination allows the RX node to extract state information immediately from the received signal without additional communication rounds, improving determination speed while the information content increase is offset by the elimination of redundant signaling
